(54) Coating adhesive strength and shear strength measuring apparatus


(57) A coating adhesive strength and shear strength measuring apparatus which can measure both the adhesive strength and the shear strength of the coating of a test piece comprises a vertical pressure sensor (15) linked at one end to a guide shaft (14) which is movable in two, vertical and parallel, directions relative to the coating surface of a test piece (S), while a parallel pressure sensor (17) is linked at its first end by a link (16) to the other end of the vertical pressure sensor (15), the second end of the parallel pressure sensor (17) being linked to a cutting knife (18) such that, as the coating of the test piece (S) is sliced with the cutting knife (18), the vertical pressure and the parallel pressure exerted on the cutting knife (18) can be measured.
